Specification of Letters Patent.

Patented Apr. 15, 1919.

To all whom it may concern:

'Be it known that I, FRANKLIN L. SHEP- PARD, a citizen of the United States, residing in Philadelphia, Pennsylvania, have'invented certain Improvements in Ranges, of which the following is a specification.

My invention relates to certain improvements in ranges of the cast metal type.

One object of my invention is to improve the range so that the oven will bake more rapidly than'heretofore.

A further ob'ect of the invention is to nfike the oven bottom detachable and renewa e.

It has been found that while all-steel ranges bake more quickly than cast iron ranges, owing to the thin metal used, yet they deteriorate more rapidly and, consequently, are objectionable for this reason. On the other hand, the cast metal range, owing to the thickness of the metal surrounding the oven, bakes more slowly and it takes a considerable length of time before the oven is sufficiently heated to bake properly, but by making the oven bottom of sheet metal I overcome this difliculty. The sheet metal bottom is renewable from time to time, but it must be supported so as to be perfectly rigid under all conditions.

In the accompanying drawings Figure 1, is a sectional plan view of one type of range illustrating my invention, the section being on the line 11, Fig. 2;

Fig. 2, is a sectional elevation on the line 2-2, Fig. 1;

Fig. 8, is a detached perspective view of the oven bottom frame with the bottom plate located therein;

Fig. 4, is a detached erspective view of the bottom frame with the bottom plate removed;

Fig. 5, is a detached perspective view of the bottom plate; and

Fig. 6, is a detached perspective view of the bottom plate inverted.

Referring to the drawings, 1 is the bottom of the oven consisting of a frame 2 having a bottom plate .3 mounted therein. 4, 4 are the sides of the oven. 5 is the outside casing of the range. 6 is the bottom of the range and between the bottom of the range and the bottom of the oven is the flue 7 connecting with the back flue leading to the chimney or stack and also communicating with the down flue 8 at the side of the oven. 9 is a products of combustion in a circuitous path through the bottom flue.

As illustrated in Figs. 3, 4 and 5, the bottom of the oven consists of a frame 2 and bottom plate 8, the frame 2 having a side flange 10 which is coupled to one of the vertical plates 4 of the oven. The frame is entirely open at the center, as clearly shown in Fig. 4, and has a flange 12 recessed at 13 to allow for the passage of the lugs 14 on the bottom plate 3, and is also recessed for the reception of the projections 15 on the opposite side of the bottom plate from the lugs, and on the bottom plate are depressions, as at 16, which aline with the depressions 17 on the frame 2 and in these depressions are pivoted turn buckles 18 which, when turned, extend over the bottom plate, holding it rigidly in position. 7

In order to hold the bottom plate rigid, I provide a support or brace 19 in the form of a secondary frame and the lugs 14 are on this support and the depressions 16 are formed therein. As illustrated in Fig. 6, diagonal braces 20 and 21 are cast integral with the support, as well as braces 22, and the support is recessed to receive the thin sheet metal plate 23, which is supported directly on the flange thus formed and on the braces 20, 21 and 22 and is secured firmly in position by rivets located at proper intervals so as to hold the plate firmly to its support. By this construction, the top of the frame 2, the support 19, and the sheet metal plate 2.3 are all on the same plane and, consequently, there are no projections to inter fere with the movement of pans into and out of the oven.

In the present instance, a flange 24 is formed on the brace 20 as well as lugs 25. The flange coincides with the flange on the bottom plate 6 of the range and forms, with the lugs, a guide to hold the flue strip 9 in proper position. While I have shown the braces 20 and 21 crossing each other at an angle to the brace 22, it will be understood that this brace may be modified according to the type of range.

In Fig. 2, I have illustrated a range having a diagonal flue strip, but in a two-flue construction, in which there is a double flue at the side, the flue strip in the bottom flue may be arranged parallel with the front, while in a three-flue construction there may flue strip or division plate which directs the be two flue strips, both parallel With the front or side, according to the location of the upper and down flues.

the bottom frame, yet Will be so thin that the oven can be quickly brought 'to the proper degree of heat for baking or roasting.

When it is desired to clean the bottom flue, this bottom plate can be entirely removed in order that access may be had to all parts of the flue. By making a skeleton support to which the sheet metal plate is secured by rivets, or other fastenings, the plate can be easily detached from the support when it is necessary to renew the plate.

I claim The combination of a' cast metal range having an oven, said oven having a main position.

the main frame, said supporting frame being detachable and having lugs on one side extending under the main frame and recessed on the opposite side to receive fastening devices on the main frame; braces extending across the supporting frame; sheet metal plate supported byv said braces and secured to the supporting frame, the upper surface of the sheet metal plate being also flush With the upper surface of the other frames; a flue strip located in the bottom flue of the range, one of the braces having a depending flangeand lugs engaging the flue strip and tending to hold the flue strip in FRANKLIN L. SHEPPARD.
